"In early September we shared that UVD2 and XvMC is coming to
Linux and that two new library files had begun shipping with the ATI
Catalyst driver: AMDXvBA and XvBAW. Earlier this month the Unified Video
Decoding 2 (UVD2) support was then enabled by default in the Catalyst
8.10 driver. These video acceleration improvements to the ATI Linux
driver aren't exactly end-user friendly yet, but today we have
information on how those interested can begin using the X-Video Motion
Compensation extension with their ATI hardware along with what the XvBA
extension will provide users in regards to advanced video acceleration
that is very similar to Microsoft's DirectX Video Acceleration."
